Figure out where to install-libs

Working towards getting crosstools working to build our cross compiler,
they use the sysroot-style installation.  We need to install our libs in
a different place depending on which style we are using.
Commit generated file to remove error/warning

This file eventually gets generated and the CXX build process completes,
but during the build we see a bunch of errors because it gets generated
too late (or something).  Its all black magic in the corss compiler
build....  We should probably revisit this at some point though.
Add working crosstools config
Backport XCC makefile to match crosstools build
Only one way of building the XCC now
Upgrade to binutils 2.24
No longer require patch to libgo for akaros
Upgrade to gcc-4.9.2
Rename patches to -akaros instead of -ros
Only set internal_function to "stdcall" on i386
fill-kfs from XCC_TARGET_LIB, not XCC_TARGET_ROOT
Upgrade to glibc-2.19
Adjust alignment for the devtab and linker funcs

The new gcc apparently wants us to have 64 bit alignment for the devtab.
We oblige accordingly.  Also changed the alignment for the linker
function sections preemptively.  Not as clear whether we needed to do
this or not, but the change was necessary for the devtab.
Add new patch to busybox for including a header
